I remember a track called "The Motorcade Sped On" by Steinski and the Mass Media (I think?) that was on a 7" single given away by the NME in the early 80s. It featured samples from what I presume was a contemporary radio report on JFK's assassination. It was very clever and very affecting.

..had a track called Death Threats on their D.o.A. album which was just a series of threats left on their answering machine. Rarely features on TOTP2.

Onomtopœia.

Hardly his finest hour, but the good stuff is so great I can forgive Todd almost anything.

By Kraftwerk on their first (double) album was lots of whistles and bangs of things falling from the sky. I seem to remember having only listened to it once a long time ago. I can't remember if they were synthesized or real sounds. Probably the former. With a bit of flute thrown in.

Released an album called Moving Parts which is, exactly that: samples of moving parts of machinery and other found sounds. It works quite well.

Metal machine Music? This is turning into the Spotify Playlist from Hell.

On Stevie Wonder's album Characters there's a song called With Each Beat Of My Heart, which samples the great man's own heartbeat.

I've got an album by a very avant-garde composer called Mira Calix, entitled Skimskitta, on which all the sounds are amplified noises made by insects. Not one I listen to much but it's quite diverting.

The title of every song on their album Happiness is just a description of the instruments on it: Cut Up Piano & Xylophone is my favourite.

Shriekback from the Care album - just the noise of some people waving long plastic rulers or thin sticks

'Who'll Fall' from Stolen and Contaminated Songs. A piece of electronic music, with a answer phone message telling one of the band members they want to jump off a cliff

rather affecting Silent Night, sung a capella over a the most monumentally depressing news broadcast ever?

Then there's John Cage's 4'33, that being the duration of a length of silence to encourage the listener to hear the noise or "music" of their surroundings.

Or the legendary lost Floyd album made with only household objects (part of which survives with the wet finger on wine glass intro to "Shine on You Crazy Diamond")

The rhythm to The Who's "Music Must Change" was supplied by Pete Townsend's footsteps echoing through his hall, as apparently, by then, Keith Moon wasn't up to keeping 6/8 time.

And of course "Billy Butlin, spoons."

from the wine bottle rattling on the top of a speaker cabinet at the end of 'Long Long Long' to 'Revolution 9' and 'I Will' and it's sung bassline that it took me twenty years to notice.

Also virtually anything off JohnandYoko's first three albums - my personal favourite being the two of them screaming their names at each other over their recorded heartbeats ... for 25 minutes. Did not trouble the charts I believe.

Methinks the "lost" Floyd LP mentioned about might be related to their (unlistenable, IMO) side project "Music from the Body", by R.Waters and Ron Geesin. This ISTR was originally going to be made up of just sounds produced by the human body, set to music via the magic of tape editing (nope, not at all the sort of idea that might land them in Pseuds Corner). The recording was duly started, but only the first track was actually completed. The rest of the LP was recorded in a more conventional fashion, so one assumes they ran out of time or budget or enthusiasm or patience or all of the above.
